Multiple CW Key Adapter Cable

I created a cool little adapter cable that allows me to connect a CW paddle (single lever) and a straight key or bug, at the same time, to the single key jack on my 6600M. I also programmed a function key button to toggle Iambic mode on and off. This allows me to operate either key without unplugging one key and plugging in the other key just by hitting a function key. This also allows my single lever paddle to act as a sideswiper key when Iambic mode is disabled. Very cool !

The cable consists of a 3.5mm stereo plug wired in parallel with a 3.5mm stereo jack (for the paddle) and a 1/4 inch mono jack connected to the tip and ground of the 3.5mm stereo plug.
